C ONFIGURING THE S WITCH
3-146
the power required by a device exceeds the power budget of the port or the
whole switch, power is not supplied.
Ports can be set to one of three power priority levels, critical, high, or low.
To control the power supply within the switch’s budget, ports set at critical
or high priority have power enabled in preference to those ports set at low
priority. For example, when a device is connected to a port set to critical
priority, the switch supplies the required power, if necessary by dropping
power to ports set for a lower priority. If power is dropped to some
low-priority ports and later the power demands on the switch fall back
within its budget, the dropped power is automatically restored.
